RIMBO, Sweden (Reuters) – Yemen’s Saudi-backed government has proposed reopening the Houthi-held airport in the capital Sanaa on condition planes are first inspected in the airports of Aden or Sayun which are under its control, two government officials said on Friday.

The proposal was made at U.N-sponsored Yemen peace talks in Sweden aimed at building confidence-building measures that could eventually lead to a ceasefire to halt air strikes by a Saudi-led coalition that have killed thousands of civilians, and Houthi missile attacks on Saudi cities.

Yemen’s warring sides agreed on Thursday to free thousands of prisoners, in what U.N. mediator Martin Griffiths called a hopeful start to the first peace talks in two years to end a war that has pushed millions of people to the verge of starvation.

Griffiths wants a deal on reopening Sanaa airport, shoring up the central bank and securing a truce in Hodeidah, the country’s main port, held by the Houthis and a focus of the war after the coalition launched a campaign to capture it this year.

Marwan Dammaj, Yemen’s minister of culture in the internationally-recognised government of President Abd-Rabbu Mansour Hadi, told Reuters Sanaa airport should be re-opened to put “an end to the people’s suffering regarding transportation”.

“But it should be a domestic airport from where Yemenis can go to Aden and then leave to international destinations,” added Dammaj, a member of the government delegation.

Hamza Al Kamali, another member of the delegation, said airplanes must stop in airports in the southern city of Aden or Sayun, east of the capital, for inspection before leaving Yemen.

The war has killed tens of thousands of people and spawned what the United Nations calls the world’s direst humanitarian crisis, since a Saudi-led Arab coalition intervened in 2015 to restore a government ousted by the Iran-aligned Houthi movement.

No talks have been held since 2016, and the last attempt in Geneva in September failed when the Houthis did not attend.

STALEMATE

The war, widely seen across the region as a proxy conflict between Saudi Arabia and Iran, has been in stalemate for years, threatening supply lines to feed nearly 30 million inhabitants.

The Houthis control Sanaa and the other most populated areas, while the ousted government based in the southern city of Aden has struggled to advance despite the aid of Arab states.

Humanitarian suffering in one of the world’s poorest countries has added to pressure on the parties to end the conflict, with faith in the Saudi-led war effort flagging among Western allies that arm and support the coalition.
